HEEL-MACHINE.

SPECIFICATION forming part of Letters Patent No. 262,902, dated August 15, 1882.

Application led August 11, 1881. (No model.)

To all whom it may concern l Be it known that I, ELBEIDGE S. MANsELL, of Lynn, in the county of Essex and State of Massachusetts, have invented new and useful lmprovementsin Heel-Making Machines; and I do hereby declare that the followingisafull, clear, and exact description of the same.

My invention relates to that class of heelmaking machines in which a block, by vertical reciprocation, operatesin conjunction with a die for cutting out lifts.

The object of my invention is, first, to provide, in combination with such a machine, a device for applying an adhesive material between the contiguous lifts, whereby said lifts are caused to adhere to each other, and the blank is formed com pactly throughout without the use of nails as preliminary holding devlees.

' In'the second place, my object is to provide means whereby the die is moved forward when the block rises, in order conveniently to receive the piece of leather from which the lift is to be cut and then to move backward to receive the pressure of the block, thus avoiding any danger of cutting the lingers of the operator.

The third object is to provide simple and Vconvenient means for giving the block lateral movement, so that the whole surface may be presented equally to the action of the cuttingdies and uniform wear be obtained.

These objects I accomplish by mechanism shown in the accompanying drawings, in which- Figure l represents a front elevation of the machine, and Fig. 2 a like view of one side. Fig. 3 is a top view of apart of the table, with the block carrying the dies. Fig. 4 is a section on line a.' a; ot' Fig. 1. Figs. 5, 6, and 7 represent details.

In these drawings the bed-plate is represented at A, with standards B B and crossbar'G, constitutingthe frame-work of the machine, which is arranged in an upright position in a suitable table or bench-board, D, as shown in Fig. l. Within the main frame is a rectangular frame, E, said frame being arranged to reciprocate vertically upon standards B, which pass through the upper and lowerbars thereof. The frameE isprovided with rods F, fixed in the ends of the frame and passing vertically down through holesA in the tablebed. They are connected at their lower ends by a cross-bar, Gr, which in turn is connected by a suitable link, H, to the treadle-arm I, whereby the frame E may be depressed by pressure of the foot, or the frame may be depressed by any suitable power applied by a crank. The frame E is pushed upward by means of springs J, placed upon the standards 6o B, said springs acting constantly to press the frame up, and with it the block N, held to the under side of the lower bar of the frame by means hereinafterl described. Within Vthe frame E is a smaller frame, e, adapted to slide 6 5 longitudinally in the larger on splines, which move between guides in the upper and lower bars of the larger frame. In this smaller frame is set the shank of the block N, being held rlirmly therein. The lower bar of the frameE is slotted, as shown at a in dotted lines, the shank passing through this slot and permitting longitudinal movement of frame e, shank, and block in relation to the larger frame. This is for the purpose of shifting the face of the block in relation to the cuttingdie.

In order to give slow backward and forward movement to the block, I provide a shaft, b, having its bearings in the uprights c c of the go frame E. Itis provided with aworm a'tthecentralpart7 which meshes into a pinion,d, the pinion dbeingpivotedupontheshank. Awrist-pin,

f, is set eccentrically in the face of this pinion 'and connected by a link and pin, g, to one of 85 the uprights c. As the pinion is turned by the worm it carries the frame e, and with it the block, very slowly backward and forward. The worm-shaft is turned by means of a pawl and ratchet at the end. The ratchet-wheel h 9o is fixed on the end of the shalt, and upon the same shaft is pivoted an arm, lc, the outer end of which is pivoted upon a supporting-rod, l, Vbeing conveniently held up by a spring, m.

A spring-pawl, o, is pivotedv upon this arm, and engages with the ratchet-wheel.

The parts are so adjusted that whenthe frame E descends, carrying with it the pivoted end ofthe lever 7c, it draws the pawl over one tooth, and as it rises it carries up the pivoted roc end of the arm and causes the pawl to turn the ratchet-wheel.

The paste-suppl yin g devices, as herein shown, consist of a paste pot or vessel, M, set upon the eross-bar n. From this a paste-tube, p, extends downward in line with the cutting-die. Near the lower end is a cock, g, the stem of which projects laterally, and is provided with a tripping-arm, s. The tripping-arm hasa pivoted latch in'the end, which, as the frame E is depressed, rides over a stud on said frame, butis turned by said stud when the frame rises, thus opening the lcock and letting a drop of the adhesive material fall from the tube. When the cutting-dies for the lifts are moved from under the cutting-block the lift last cutout and packed in the die is broughtI under the pasting apparatus. The cutting dies or c ntters are mounted on a movable plate, P, which moves from front to rear upon a guide-rail, r. It is caused to reciprocate by means of arms tt, fixed upon the rock-shaft T, mounted in= hangers U beneath the table. Another fixed arm on this shaft extends horizontally,v and through a. hole in itsend passes arodconneet! ing the arm to the treadle-lever. The connection of the rod with the arm u is made by means of a button and spring interposed between the button and upper side o f the arm.

t precise mechanism herein shown for applying The arms t t are slotted at their upper ends to receive pins iixed in the plate P. Depression of the treadle moves the plate backward,

and it is moved forward by means of the springs J, through the connections, as described'. The

spring between the button and the arm a is.

for the purposeof allowing movementof the frame, which brings down the block after the.,

plate P has reached the limit of its movement,

and thus brought the cutting-die into place. The limit of its movement to the rear is deterl shape, andthe leather or material placed bemined by the lengthy of thev slots in which the arms t t move, and after vthey have reached their limit of movement to the rear further inotion of the treadle completes the movement of the block N.

It will be understood that the movements described are so timed, that the plate P, carryin g the block in its forward movement, passes under the paste-tube at the instant when the cock is opened (the cock being openedbut for an instant) to allow the paste to escape.J I he plate P is moved far enonghto the front from under the block, asfbefore stated, to allow the operator to place the leather upon the die, and

then the plate is moved back to its place beneath the block, which, as it descends, presses.

the leather upon the die, whichcuts theleather into the shape demanded by the die, the leather being forced into the die.

In order to form what are known vintlietrade as deck-heels77 it is necessary to provide cut'- ting-dies of two sizes, and this requires also,l that the relative positions of the cuttingdies edge of the inner.

outer die is formed with a bottom cut with an opening adapted to tit accurately over the parallel sides of the inner die. The outer die is marked 2. 1t rests on the horizon tal faces of two wedges which work in guideways across the block P. These wedges are so adjusted that when thrown back they lower the outer die until its edge is a little below the When the wedges are pushed forward they raise the outer die until the position of the edges is reversed, those of the outer die being a little above the edges v of the inner. The two wedges marked 3 3 are lcon-nected by a cross-piece, 4, through which .1a screw passes, having its inner end, which is threaded, passing into a threaded hole in the plate P. The part which passes through the cross-piece 4. isprovided with collars, by means fof which, when it is turned in or out,it carries Jthe QIOSS-,pieceibrward or back, and thus advanees o r` retracts the wedges. Any suitable `n a'eans may be used instead of the screw for moving the wedgesback and forth. The pressure spreads the adhesive material between the ilifts and causesy it to adhere throughout the i whole surface-fa compact and solid heel-blank.

I do not desire to limit my invention to the paste toeach lift to enable the series of lifts to .be held together by paste instead of nails; nor idol. desire to limit my invention to the employinent of wedges as the adjusting mechan isin by which the relative vertical position of the outer. and inner. cutting-die is changed,

lso that the edge of one may be thrown to a 'position above the other and be held there, instead' of being removed.

The cutting-die used may be of any usual tween the block and die will always be cut intoashape corresponding with the shape of the die.

Having thus described my invention, what I? claim is 1. Ina machinefor cutting lifts and forming heel,-blanks,a cutting-die and block, whereby the lifts are cuty and pressed intothe die, and mechanically-operatin gpastin g devices adaptedtosupply paste or adhesive material to each of the said lifts as cut, the partsspecifled be- IOO IIO
